Using this watch is easy. Just adjust the strap to fit your wrist comfortably. To set the time, pull out the crown gently and turn it to the correct time, then push it back in. When wearing the watch, avoid hitting it against hard objects to prevent damage to the case or the diamonds. Also, keep it away from water for extended periods, even though it's water-resistant up to 5 ATM. For maintenance, clean the watch regularly with a soft, dry cloth to keep it looking shiny. If you notice any issues with the movement or the strap, it's best to take it to a professional watch repair service.
